The stock gearing on my Hawk 250 was a little bit low, great for trails and woods riding but I wanted to be able to do 50-55 mph to work without redlining so I swapped out for some higher gearing.

Always make sure to set your torque wrench back to the lowest torque setting before storing. The spring inside will develop a memory and throw off the accuracy.

That's wild, i cant believe they gear the hawk so low. I got the bsr Raven, its stock is 17/46. Good video btw 😁👍 upgrading mine to 17/42 since I do primarily back road and gravel. Very excited to be able to run at 55 without all the vibration of pinning it at 6500rpm 😅

Just did sprockets and o-ring chain on my brozz. Since I do more commuting than dirt I went with the 17/40 and love it. I can run 60 mph at 6100-6200 rpm now. First three gears will do me good on dirt roads and easy trails still. If I can find a little more top end power, 65 mph will be a do-able cruising speed on relatively mild terrain.

@jpaulie2008 2 года назад
@@user-km5kj8xh1x I found 17-40 for more road oriented, 17-42 would be just a little higher rpm and probably a few mph less then that. I could probably drop to a 42 sprocket, but I am looking at finding a few more hp to make it work. It really is all up to how you use your own bike what is best for you.

Thanks! It's an option, things have been working really well so it's not a top priority. But I do have a rear shock I want to do and I might do the swingarm bearings at the same time. Word on the the street is the stock ones have no grease in them.

@@skydcontrol sure thing. Also, the brake caliper bolts should be torqued to 22 ft-lbs. The rear axle nut should be torqued to 35 ft-lbs, not 65 ft-lbs like the Hawk manual says. I’ve seen a few swingarms collapsed with 65 ft-lbs. See the TT250 online manual here for torque specs: cscmotorcycles.com/tt250-rear-wheel-removal-and-re-installation/ Most Hawk guys use those.

So, when changing out both sprockets, does the stock chain just fit right into place? I would have assumed (not know anything about anything) you needed a new chain that would line up and fit properly.
@skydcontrol
@skydcontrol Год назад
It depends on how much you change it. For example I came down a few teeth on the rear sprocket but went up 1 on the front. Then there's an adjustment that in my case took up the extra slack. In some cases you would need to take a few links out of the chain for sure.

Did you put grade 8 bolts or the ones it came with ? On the important components in general
@skydcontrol
@skydcontrol 2 года назад
I used the stock bolts, Grade 8 bolts have a high tensile strength but are also brittle and not really needed in this case. If I was going to replace the stock bolts I'd probably just use grade 5.

@skydcontrol
@skydcontrol Год назад
The 520 chain isn't necessary but you surely can upgrade to it if you like, it'll take a bit more of a beating. 13/40 will surely lower your RPM's but at the cost of low end torque. I don't think this is too far off my setup of using the 428 chain and 16/45. In fact I think my setup is a little higher geared. check out www.gearingcommander.com/

Just remember that if you lose a tooth you also lose power And when you on a steep climb that is when you will notice it.
@skydcontrol
@skydcontrol Год назад
You don't lose power, you're changing the ratios and therefore how the power is transferred. It's a trade off though, if you need more top speed you're gonna lose the lower end crawl. This setup has worked well for me. I think it's a good compromise.
@donaldgrant9067
@donaldgrant9067 Год назад
@@skydcontrol That is what I meant by losing power. You give up a little low end going down a tooth. I probably didn't use the right term. But thought it is important the people understand that if they are using the bike off road. a lot of people today don't even understand what you are doing and why changing gears do. For an example I have a Chinese 250, you buy what you can afford and used dirt bikes are $4500 minimum, it came with a 40 tooth rear sprocket and I put on it a 48 tooth to get more low end power. It's a dirt bike and not an enduro, so I don't need to go 70 on the dirt. 55 will be just fine.
@skydcontrol
@skydcontrol Год назад
@@donaldgrant9067 I agree, 55 is plenty for me as long as I'm not winding the engine out and it leaves me enough down low for low speed control off road. Also, makes wheelies easier too 😁

@@skydcontrol I have the Appallo 250 and the problem I had was getting up the motorcycle ramp into my 4 wheel drive pickup. Kept stalling out just about the time I got to the top. I dropped it twice and decided that I needed more low end power. So I went with the 48 tooth. I've got a Chinese 2 stroke coming and I'll let you know about that. Those of us that can't afford a KTM need a good bike to ride on the dirt. After all we the working class were the ones who started dirt bike riding. Oh how's your knuckle. That always hurt when you hit it.
